Blocana Developer Documentation

Everything you need to build powerful, scalable, and quantum-resistant applications on the Blocana blockchain.

Quick Start Guide

1. Install Blocana SDK

npm install @blocana/sdk

The Blocana SDK provides everything you need to interact with the Blocana blockchain, including transaction creation, account management, and smart contract deployment.

2. Initialize the Client

import { BlockClient } from '@blocana/sdk';

const client = new BlockClient({
  network: 'testnet',
  apiKey: 'YOUR_API_KEY'
});

Connect to the Blocana network by initializing a client with your API key. You can generate an API key in the developer dashboard.

3. Create Your First Transaction

const transaction = await client.createTransaction({
  from: 'YOUR_WALLET_ADDRESS',
  to: 'RECIPIENT_ADDRESS',
  amount: '1.5',
  data: '0x' // Optional data payload
});

const signedTx = await client.signTransaction(
  transaction, 
  'YOUR_PRIVATE_KEY'
);

const receipt = await client.sendTransaction(signedTx);
console.log('Transaction hash:', receipt.transactionHash);

Create, sign, and send a transaction to transfer tokens or interact with smart contracts on the Blocana blockchain.

4. Deploy a Smart Contract

const compiledContract = await client.compileContract(
  contractSourceCode
);

const deployTx = await client.deployContract(
  compiledContract,
  [/* constructor arguments */],
  'YOUR_PRIVATE_KEY'
);

console.log('Contract address:', deployTx.contractAddress);

Compile and deploy smart contracts directly from your application using the Blocana SDK.

Simple Token Transfer

JavaScript
// Send tokens to another address
const tx = await client.sendTokens({
  to: "0x123...abc",
  amount: "10.5",
  gasLimit: 21000
});

console.log(`TX Hash: ${tx.hash}`);

Smart Contract Interaction

TypeScript
// Load a deployed contract
const contract = client.loadContract(
  contractAddress,
  contractABI
);

// Call contract method
const balance = await contract.methods
  .balanceOf("0x456...def")
  .call();
View full example

Event Subscription

Python
# Subscribe to contract events
subscription = client.subscribe(
    contract_address,
    event="Transfer",
    from_block="latest"
)

for event in subscription:
    print(f"Transfer: {event}")
